ADJUSTABLE BEVEL.

SPECIFICATION forming part of Letters Patent No. 593,987, dated November23, 1897. Application led April 28, 1897. Serial No. 634,231. (Nomodel.)

To af/ZZ whom it may concern:

Be it known that I, JOHN F. CRESS, a citi- Zen of the United States,residing at Mahanoy City, in the county of Schuylkill and State ofPennsylvania, have invented certain new and useful Improvements inAdjustable Bevels, of which the following is a specification, referencebeing had therein to the accompanying drawings.

The object of my invention is the construction of an inexpensive andcompact doubleextension bevel susceptible of having two or more bladesat each end of the case by which two bevels may be taken at one and thesame time, with means to take lineal measurements, the blades to behoused within the case when not in use; and I attain my objects by themechanical means hereinafter described and claimed.

In the drawings, Figure 1 is an isometric view of my device, the bladeshoused, but shown extended and ready for use in dotted lines. Fig. 2 isan isometric view thereof, partly in section, the top of the housingremoved and turned over, the blades at one end withdrawn from the case.Fig. 3 is a side view, the blades extended from the case and displayed.Fig. 4 is a section through line 4 4 of Fig. 1. Fig. 5 is a sectionthrough line 5 5 of Fig. 1.

Like characters of reference indicate the same parts in the views.

The case A consists of the sides 5 and 6, the top 7, and a bottom 8,which is the duplicate of top 7. The top and bottom are rigidly attachedto the sides by screws. The heads B have rigidly attached thereto theguides 9 9' and 10 10', which extend inwardly and conform to and operaterespectively in the grooves Il 16 and. l2 and 15, located in the top andbottom of the case for their reception. The guides 9 9 each have theslot 17 for the reception in each of the fiat-headed bolts 18, having arectangular shank and carrying the washers 19 and countersunk nuts 2O onthe outer side to form a stop in the outward extension of heads B andrigidly hold the head at any desired point under the limit of itsextension. I do not confine myself, however, to the use of the describedwashers, because if the sides of the case be constructed of metal thewashers may be dispensed with.

The slotted blades 2l 21 and 22 22 are adj ustable upon the bolts 23,which are held from turning` in place by the elongated countersunkbolt-heads 24. The blades are adjusted at any desired angle by means ofthe nuts 25 on the end of the bolts 23, Fig. 4, operating against washer26 or operating against sides of heads B, if washers are dispensed with.The blades are held from undesired lateral movement in the head by theblocks 27, through which the bolts 23 pass. The blades 21 2l and 22 22conform to and may be operated in grooves 13 and 14, respectivelylocated in the top and bottom of the case for the reception of theblades when housed within the case. The guides 9 9 carry a scale ininches and parts of inches, as shown at 28, for use as the operator ofthe device may find the same convenient.

The operation of my device is as follows: By a pull on the heads B theblades may be drawn out of the case. The heads may be rigidly held atany desired 'distance within the length of the guides 9 9 by pressureapplied to the guides against the side of the case through the nuts 2Oon the ends of the bolts 18, the inner bearing being supplied by thefiat-head of the bolts. The operation of the blades is plainly apparent.

Having described my invention, I claim- 1. In a bevel in combinationwith a case having grooves, a blade pivotally attached to a head at oneend and arranged to fold backward in line with the guide and to enterthe grooves in the case to house the blade, as and for the purposes setforth.

2. In a bevel a housing-case provided with multiplex grooves for thereception of guides and blades attached to heads at each end of thecase, guides rigidly attached to the heads and operating within thegrooves, means to regulate the extension of the heads carrying theblades, slotted blades adjustable in the heads and arranged to foldbackward in line with the guides and to enter the grooves in the case,means for holding the blades in adjustment at a desired angle and meansfor regulating the extension of the guides, as and for the purposes setforth.

In testimony whereof I affix my signature in presence of two witnesses.
